Does Blender 2.8 work with Nvidia 1050 Ti graphics?
Is this what your preferences looks like?

If there is a card showing up there, then you need to check the checkbox next to it. If not then I am quite lost, since there isn't really a reason a gtx 1050 ti wouldn't work with blender, except if you have an outdated driver or something. As far as I know all of the 10th gen Nvidia cards work in blender 2.8 (I personally had a gt 1030 work fine).

P.S. If this doesn't work, please clarify what OS you are using.
